I'm not trying to drag you back into this, but...You asked for a source. I'm not saying that I agree with the author on every point. I simply think he makes some good arguments that are relevant to our conversation.
Don't you think that referencing Hirst, apparently a Methodist with no regard for the RPW, might be ever so slightly problematic when arguing a Reformed view of worship?
But I'm going to give this discussion a rest, too, at least for the weekend. I will finish reading this chapter of the book, though.
